JAMES KEITH, OF LONDON, ENGLAND.

RADIATOR.

SPECIFICATION forming part of Letters Patent No. 599,611, dated February 22, 1898. Application filed March 25, 1896. Serial No. 584,871. (No model.) Patented in England October 10, 1394,11'0. 19,233.

To-aZZ whom it may concern.-

Be it known that I, JAMES KEITH, of London, England, have invented certain new and useful Improvements in Radiators for Heating and Ventilating, of which the following is a specification.

The invention has been patented in England, No. 19,233, dated October 10,1894.

It is the object of my invention to provide a sectional form of radiator in which the air will be directed through the spaces between the sections by panels placed in the front of the radiator. The panels reach to a point slightly above the floor, being held by suitable pins on the radiator-sections, which sections have also lugs at their front side bearing against each other.

In the drawings, Figure 1 is a perspective view of the invention. Fig. 2 is a side view of a section of radiator slightly modified from Figs. 1 and 3 and in which there are three I vertical tubes to each section instead of two,

as in the other figures. This figure shows how air may be supplied 'to the radiator. Fig. 3 is a plan View in section. Fig. 4 is a horizontal section of the radiator of Fig. 2.

Each section of the radiator comprises front and rear tubes A B, connected at top and bottom and with air-spaces D between them and between the sections. The flanged portions E'of the rear tubes are connected by nipples F.

The complete structure is supported, by the feet G.

Fig. 2 represents a modification in which three tubes are used for each section,(marke'd A, B, and O.) In this form the nipples at F are arranged between the central tubes of the radiator instead of between the rear tubes, as in Figs. 1 and 3. I

Fresh cold air is fed to the radiator through the opening I below the same and in the floor. This opening is controlled by flaps or doors J J, Fig. 2, which when raised abut againsta portion of the radiator and thus provide partitions, which forth between them a coldair duct for directing the air to the spaces D of the radiator. The nipples F or F may be screwed into and out of place by a tool engaging the ribs or projections L. Panels N, ornamented or plain, are inserted loosely between the sections at the front, for which purpose they have small projections'engaging the recesses O in the fins P, extending vertically of the radiator. At the frontthe sections of Figs. 1 and 3 have laterally-proj ectin g lugs Q, which abut against each other at a slight distance above the floor, these lugs forming a horizontal division-wall below which the cold air can be drawn into the radiator from the room, supposing, of course, that thefiap J is closed. The lugs are within the vertical plane passing through the fins. The panels N are located above the lugs Q. These lugs and the flanges Eat the rear of the sections are faced to form lateral bearings between the parts, and when the sections are screwed together the panels will be held in placeby the fins. Ornamental pieces B may be slipped over the joints between the lugs Q.

In Figs. 2 and 4 the sections have the lugs Q at both the front and the rear thereof.

When the flaps J are raised, they contact with the lugs Q.

A board or cover S may surmount the radiator.

Having now described the invention, what I desire to secure and claim by Letters Patent is- 1. In combination in a radiator the sections made up of a plurality of tubes, nipples connecting the sections, each of the front tubes having a projecting vertical fin with a lugQ projecting laterally from said front tube and within a vertical plane passing .through the said fins, the said lateral projections abutting against each other and the air-directing panels fitting over the said contacting lugs and between the fins, substantially as described.

2. In combination, the radiator-sections,

.each section being made up of a plurality of tubes, the nipples between the sections, the fins extending vertically of the front tubes, the lugs projecting laterally of the front tubes and-within a vertical plane extending along the fins, said lateral lugs being in contact at a point above the floor, the air-directing panels fitting between the said fins, the air-opening beneath the radiator, and the flap controlling the same, said flap when raised being in contact with the lugs to thus form a continuation downward of the air-directin g channel, substantially as described.

Signed at London this 23d day of December, 1895.
